[Winpcap-users] Sending packets upwards (to local IP stack)

[Gianluca Varenni]

It's not possible with WinPcap. With WinPcap you can only send/receive packets to/from the lower layer i.e. usually the network card. In order to inject packets back to the IP stack you would probably need an NDIS intermediate (IM) driver, or a virtual miniport.

Have a nice day

  Hi,

   

  I'm trying to replay messages from machines located on a VPN connection by spoofing their IP when sending the packages. It works fins because we send the packages to our self and the router/switch will return the message that we sent back to us. But I do not want to rely on this and some packages are of multicast type so other machines might get them and they have no valid route to the source IP. What I wonder is if it is possible to generate a package only to our local machine but instead create an incoming message instead of an outgoing. Is this possible? 

   

  Best regards,

  Bengt Werstén
